Ubiquitin is a small (8.6 kDa) regulatory protein found in most tissues of eukaryotic organisms, i.e., it is found ubiquitously. The addition of ubiquitin to a substrate protein is called ubiquitylation (or ubiquitination or ubiquitinylation). Ubiquitylation affects proteins in many ways: it can mark them for degradation via the proteasome, alter their cellular location, affect their activity, and promote or prevent protein interactions.[4][5][6] Ubiquitylation involves three main steps: activation, conjugation, and ligation, performed by ubiquitin-activating enzymes (E1s), ubiquitin-conjugating enzymes (E2s), and ubiquitin ligases (E3s), respectively.

Dopamine (DA, a contraction of 3,4-dihydroxyphenethylamine) is a neuromodulatory molecule that plays several important roles in cells. It is an organic chemical of the catecholamine and phenethylamine families. Dopamine constitutes about 80% of the catecholamine content in the brain. It is an amine synthesized by removing a carboxyl group from a molecule of its precursor chemical, L-DOPA, which is synthesized in the brain and kidneys. In the brain, dopamine functions as a neurotransmitter—a chemical released by neurons (nerve cells) to send signals to other nerve cells. Neurotransmitters are synthesized in specific regions of the brain, but affect many regions systemically. The brain includes several distinct dopamine pathways, one of which plays a major role in the motivational component of reward-motivated behavior.

[whats-in-a-sentence]

JA acts through a conserved ubiquitin ligase-based signaling mechanism that bears close resemblance to those described for auxin and gibberellin (Figure 23.19). (...) Two additional proteins and two histone deacetylase enzymes (HDA6 and HDA19) act as co-repressors asking with the JAZ-COI1 complex and are instrumental in maintaining the chromatin in an inactive state (see Figure 23.19). The binding of JA-Ile to the JAZ-COI1 co-receptors leads to the ubiquitination of JAZ by the SCF^(COI1-JA-Ile) complex, followed by JAZ degradation via the 26S proteasome (see Figure 23.19).

The plant hormones jasmonate and gibberellin also promote the interaction between an F-box protein of a SCF ubiquitin E3 ligase and its transcriptional repressor target proteins (Figure 15.34B and C).

oh you want cursed biochem acronyms? good god i’ve got some absolute Bricks to share.

piRNA - PIWI interacting RNA

PIWI and RNA are also both acronyms

PIWI - p-element-induced wimpy testis

yes they’re nesting acronyms now. yes i hate it.

UHRF1 - "ubiquitin-like, containing PHD and RING finger domains, 1"

once again PHD and RING are both acronyms. STOP NESTING ACRONYMS

PHD - plant homeodomain

RING - really interesting new gene

reading papers for genetics/biochem courses is like. ah how many random sequences of letters can we cram in here before people start calling bullshit. and apparently? it’s a lot.

today i googled GPS looking for 'global protein stability', and was completely shocked when i was reminded that there is a much more common use for that acronym. please share any more cursed acronyms you know in the notes!

letter sequence in this ask matching protein-coding amino acids:

protein guy analysis:

this structure does a wonderful job illustrating the difference between secondary and tertiary structure. there is a decent amount of secondary structure, with lots of alpha helices of widely varying lengths. however, they do not actually come together to make anything. that is why, when you look at the surface, it is more holes than protein. it seems that unnatural, random proteins with a hydrophobic core may be more likely to aggregate and therefore more dangerous to the cells, but i'm not expressing these in anything anyways, so i still think it would be nice to have a good-looking image.

Several of the most prevalent new-onset autoantibodies have, to our knowledge, not been described previously, including the three with the highest prevalence, i.e., anti-CCDC63 (coiled-coil domain-containing protein 63), anti-TRIM63 (E3 ubiquitin-protein ligase TRIM63), and anti-SNURF (SNRPN upstream reading frame protein)

Scientists in Canada and the U.S. have discovered a new way in which Ebola—an often deadly virus affecting people mostly in sub-Saharan Africa—reproduces in the body. By shedding light on how the virus interacts with a human protein called ubiquitin, the researchers have also identified a potential target for new drugs to prevent the disease.

Podocytes are cells in Bowman's capsule in the kidneys that wrap around capillaries of the glomerulus. Podocytes filter the blood, retaining large molecules such as proteins while smaller molecules such as water, salts, and sugars are filtered as the first step in the formation of urine.

SUMO (Small Ubiquitin-like Modifier) proteins are a family of small proteins that are covalently attached to and detached from other proteins in cells to modify their function, via a process is called SUMOylation. SUMOylation is a post-translational modification involved in various cellular processes, such as nuclear-cytosolic transport, transcriptional regulation, apoptosis, protein stability, response to stress, and progression through the cell cycle.

In my senior year of highschool we had a final project in AP Biology which was open-ended and could be just about anything. I rewrote (and performed) Thrift Shop to be about various branches of biology using the terminology that we had used that year. I titled it "Niche Shop."

These are the lyrics.

^ So you can follow along.

Hey… You wanna go niche shopping?

I’m an organism I’m alive You can tell by how all my cells utilize I’m- I’m- I’m growing, adapting and I’m showing, This is my response

Walk into a niche like what up I’m an organism Organ cells, organelles, carbon-based organ systems If I’m surviving, got the traits you wanna copy Got ‘em like- “Damn, I better acquire mimicry”

Factor in, fitness my kin Nat select me as a king Dressed as a warning or I’m camouflaged from everything The strongest or the fastest, sharper than Damascus But if you really wanna live, you gotta have looooong… Telomeres!

Hoofin’ it, wingin’ it, gonna optimal forage it Passin’ up through the TD forest Humus is a freebie nourish Not rockin’ semelparity but, I am a rarity 1.8 meters too much room for a disparity!

An issue of polarity, Irregularity of molarity, Disrupts cellular activity Lacking biologic dexterity

Dehydration synthesis, poly or di Covalent bonding with all the mama-saccharides!

They had an H ion, I took an H ion For ETC so I can have the energy to hang on Mito makes a maze of its membranes To gain energy used in transduction signal pathway chains

I could take some bases, Rough ‘em up and misplace The wild types would be like “Oh, he got the lactase”

I’m gonna eat some carbs I need energy and I’m on guard I’m- I’m- I’m drinking, drying and I’m linking, This is glycosidic

I’m gonna bond some peptides There are four structures so please stay wise I’m- I’m- I’m asking, amino group and acid, But don’t forget nucleotides (AUOHW!!)

What’chu know about being hydrophobic? What’chu know about being hydrophilic? I’m diffusion’, I’m movin’ right through that fatty bilayer Meet the mosaic and all its necessary players!

Thank Aunt Ester, for linking glycerols and fatty acids It’s an asset keep ‘em like molasses Metabolism, you can have in catabolic (bolic) Minus delta G or you can have it anabolic (bolic)

Prokaryotes, no nucleus All have membranes like eukaryotes Cyto-structure and ribosomes and DNA in that cytoplasm Eukaryotes have organelles in that cytoplasm Lysosomes and vacuoles in that cytoplasm

They’re like “oh, that peroxisome, that’s hella tight” I’m like “yo… that makes hydrogen peroxide” Competitive inhibition will render us quickly illin’ Catalyse that catalase to cure our condition

Don’t forget, ‘bout the mosaic composition Don’t forget, about what lets somethin’ else in That receptor is hella though But havin’ a common one in a pandemic is a hella NO

Peep gang, come take a look at my DNA Find all the nights I spent with retroviral RNA

[Interlude] In your DNA … viral RNA … turned to DNA … and then to RNA Immune … poppin’ cells … yeah!

I’m gonna place some tags Ubiquitin be quittin’ on all these proteins This cellular machine, RNA in vaccines An acid for every codon

I made God to be in my image All these kids descend from my lineage I have eternal DNA My fitness is secured through advantageous traits [X2]

As DNA replicates Every cell from a cell - this never dates I’m- I’m- I’m growing, adapting and I’m showing, This is my response

Are those your Grandpa’s genes?
